Manchild (UK)

Four male friends in their 50s try to navigate through life and mid-life crisis. Two of the four near/post 50 year old men are divorced men (Head and Havers), one never married (Warrington), and one is still married (Burdis). Head and Havers like playing the field (though Head has a problem crop up very early on) and Burdis likes being married, but is still interested in women.
